Our said invention relates to a machine for treating tile and more particularly to that art of the machine adapted for cleaning t e respective "surfaces of the tile, the

99 Figure 3.

In the drawings reference character 10 indicates side frame members jointed by crossbars 11 and which may be supported by suitable legs (not shown) Standards 13 are 'mounted at each'side of the machine on the side bars or frame members 10 and serve to support two pairs of coacting brushes 14, 15, 16 and 17, one of the brushes of each pair being disposed above the other in substantially vertical position and between which pairs of brushes is mounted a pulley 18 about which travel bands 19 and 20 and 21. The bands 19 and 20 serve to bring the tile between the first set of brushes 14 and 15 and the bands 21-serveto carry the tile outward between the second set of brushes 16 and 17; The band or conveyor is provided with a series of cleats 22 arranged to engage the tiles and cause them to be carried along by the conveyor 20 positively into the cleaning mechanism of the machine. The cleats 22 are spaced apart on the conveyor 20 in a manner to permit tiles of various standard sizes to be easily placed therebetween by the operator, thereby permitting the tiles to be inspected by the same operator. Rails 23 are supported on adjustable brackets 24 provided to guide the tile through the cleamng mechanism. Each cleaning brush is supported at each end on stub shafts 25 which are carried in bearing blocks 26 slidably mounted in the standards 13 so that the conveying bands it becomes necessary brushes may be adjusted vertically by means of screws 27 and 28. The screws 27 being arranged to control the adjustment of the upper brushes 14 and 16 and the screws 28 bemg arranged to control the adjustment of the lower brushes 15 and 17. The stub shafts 25 are provided with collars 29 having on their side faces laterally projecting pins 30 for affording a drive for the brushes. On the stub shafts at one end of the brushes are mounted driving pulleys 31 by means of which the brushes are rotated during the passage of the tiles on the conveyors through this part of the machine. The stub shafts 25 are retained against endwise movement in their bearing blocks by means of collars 32 which may be secured by set screws 33 to the shafts. With this construction should it become desirable or necessary to renew one of the brushes the collar at the inner side of the bearing blocks may be loosened and the end of the shaft pulled out of the end of the brush after which the brush can be easily removed. The brushes all rotate in a direction reverse to the direction of movement of the tile as they are carried through the machine and they brush not only the upper and lower surfaces but also the side edges .of the tile. A belt 34 may be used for operating both sets of brushes, such belt eitending under brushes 1-5 and 16 and over brushes 14 and 17 to cause the adjacent surfaces of the coacting pairs of brushes'to move in the same direction. A tension pulley 35 is adjustably supported in a bracket carried on one of the side frame members 11 of the machine for varying the tension of said belt 34.

It has been found desirable to use two sets of brushes in order to thoroughly brush both faces of the tile to remove foreign matter whether in the form of loose particles or material adhering to the tiles and also since the lower brush of the first set of brushes cannot come in contact with that part of the bottom of the tile which directly rests upon and engages the upper portion of fihe t at the remaining portion of the bottom of the tile be brush. This is accomplished by arranging bands 21 in different relative positions from the bands 19 and 20 so that the unbrushed portion of the tile becomes exv posed to the action of the lower brush 17 of the second set of brushes.

Tiles of certain sizes and shapes, when placed on the conveyor belts will occupy the greater part of space between the cleats while two smaller tiles of an elongated form may be placed between the cleats.

It will be obvious to those skilled in the art that various changes may be made in our device without departing from the spirit of the invention and therefore we do not limit ourselves to what is shown in the drawings and described in the specification but only as indicated in the appended claims.

Having thus fully described our said-invention, what we claim as new and desire to secure by Letters Patent, is:

1. In a machine for treating tile, the combination of conveying means, means dis posed above and below the conveying means for brushing the upper and lower} faces of the tile durmg its movement, a second conveying means offset from the first mentioned conveying means, and a second set of brushes associated with the second conveying means for brushing the portion of the tile not operated upon by the first set of brushes, substantially as set forth.

2. In a machine for treating tlle, the combination. of upper and lower coacting brushes, a conveyor extending between the coacting brushes for carrying tile therebetween in order that they may be operated upon bysaid brushes for cleaning the same, a second conveyor offset from the first mentioned conveyor, and a brush coacting with said secondconveyor for engaging the portion of the tile not operated upon by the first set of brushes, substantially as set forth.

3. In a machine for treating tile, spaced pairs of superposed brushes, a pulley disposed between said pairs of brushes and having grooves about its periphery for engagement by conveyor bands, and conveyor bands extending about said pulley in ofi'set relation for conveying tiles to be cleaned between said brushes the arrangement being such that the under surface of the tile not acted upon by the first set of brushes will be acted upon by the second set of brushes, substantially as set forth. 1

In witness whereof, we have hereunto set our hands at Anderson, Indiana, this 9th day of May, A. D. nineteen hundred and twentyseven.
